maybe someone here can help me: i think my little macbook's ethernet port is screwed. I have done the following tests: plug in the same cable to my macbook pro. (working) plug in a different cable to the macbook. (not working) check the port see if anything is broken. (pins are fine) wireless on the macbook (working) Restart the computer, repeat the tests (still not working) what is happening here? all of the sudden... well after i unplug the cable, plug it back in. Any suggestions here? Appreciate your time.
